Donald Trump will sign an executive order in hopes of favoring American workers by reforming the H-1B visa program and minimizing exceptions to the Buy American Act of 1933, which requires the federal government to favor U.S.-made products when funding projects.

The president is scheduled to sign the two-part order — Buy American and Hire American — after delivering remarks at a tool manufacturing company in Wisconsin Tuesday.

The first part of the executive order — Hire American — seeks to enforce the H-1B visa program so it “serves the national interest” by awarding visas to the most-skilled and highest-paid applicants without bypassing American workers who are qualified for those jobs.

Though Trump vowed to end the H-1B visa program as a candidate, a senior administration official said the order instructs the Department of Homeland Security, the Department of Labor, the Department of Justice and State Department to propose reforms to the program to prevent fraud and abuse in the immigration system.
